Energy consumption type rolling stone protection system and energy consumption type rolling stone protection system design method

Abstract

The invention discloses an energy consumption type protection system. The product is arranged on the slope surface of a massif where rolling stone happens. The energy consumption type protection system comprises two levels of energy consumption structures. The first-level energy consumption structure is an energy consumption plate device, and the second-level energy consumption structure is an energy consumption piston device. The energy consumption plate device comprises an energy consumption panel facing the slope aspect, the energy consumption panel is fixed to a rolling stone impact area through a hinge frame, and the energy consumption panel is formed in the manner that a metal grid frame is filled with energy consumption material block single bodies. The energy consumption panel is connected with a piston rod of the energy consumption piston device through an inhaul cable. A piston air cylinder of the energy consumption piston device is fixed to the non-rolling-stone impact area, and the piston air cylinder is provided with a vent valve. According to the system, different energy consumption principles are comprehensively adopted for acting, and the overall energy consumption efficiency is high. The invention further provides an energy consumption type protection system design method. In cooperation with the design method, a standard part can be adopted in the system for designing and machining, the field construction speed is high, the project quality is easy to control, the energy consumption type protection system and the energy consumption type protection system design method can be applied to alpine and gorge regions where construction is hard through a traditional structure, and rescue and relief work is convenient.

Description

technical field [0001] The invention relates to a structure of a rolling stone protection system and a design method thereof, in particular to an energy-consuming protective structure and a design method thereof for preventing and controlling mountainous slope rolling stone disasters, belonging to the fields of disaster prevention and control engineering in mountainous areas and road and bridge engineering. Background technique [0002] The construction of traffic routes needs to go through mountainous areas. Road construction in these areas involves a lot of slope excavation and support problems, and the problems of dangerous rock collapse and rolling stones on the slope are prominent. Especially in accident-prone areas, a large number of rolling stones and falling rocks often damage the road or even injure lives, causing accidents and blocking emergency rescue. There are two types of protection against rolling stones, one is active protection, which prevents rolling stones...

Problems solved by technology

However, both theoretical analysis and engineering practice have shown that ordinary passive protective nets have the following technical defects: First, the metal flexible net has more than enough flexibility but insufficient strength, and it is often damaged by one-time direct breakdown when facing the impact of high-speed and high-energy rolling stones; On the one hand, falling stones impact on the steel column, and the steel column will be directly damaged due to insufficient strength of the steel column; Transmission of uneven loads to the steel column often leads to twisting and damage of the steel column on one side due to the large bending-torsion action, which fails to achieve the expected protective effect; the third is that the metal flexible mesh and the decompression ring are non-modular production components , when the flexible net is punctured and damaged, the overall protective structure is completely paralyzed, and the protective net needs to be completely removed during maintenance, which is complicated and wastes resources
